Application filed August 18, 1924. Serial No. 732,716.

@ZZ 'w72 om "it may concern it known that l, dossier inoaniinan, ect et the lling; et Great Britain, and resident et the city et i" -t-on, in the Frovince of alberta and Dominion ot' Canada, have invented certain new and useful improvements in Foists, 'ci' which the toilowing is a speciticatien.

This invention relates to improvements in hoists and the objects of the invention are. to provide an etllcient and adjustable hois that can be quickly assembled or collapsed and which is designed, particnlariy in hoistin Y ianos and the like, to swing out through a window into hoisting position.

Further objects are the provision of a hoist of this character which can be adapted to tit any window of a building and which can be adjusted to operate from within, thus avoiding' any danger to the operator by having' to stand ont-side on the window sill when hoisting pianos or other articles into a building. l

iith the foregoing and other objects in ri the invention consists essentially in the novel arrangement and construction of parts as described in the accoinpaying speciiica tion and illustrated by the accompanying drawings, formino' part o'l vthe same.

Referring now to the drawings in which like characters of reference indicate corre` .spending parts;

Figure 1 is a side elevation, part in section of a window in a building fitted with my improved hoist in. a lowered position.

Figure 2 is a similar View showing the hoist with a. load ready to be swung inwardly.

Figure 3 is a plan View of the swingable member ot the hoist.

Figure 4 is a sectional detail of the means for joining` the parts of the swingable member.

F igure is a section on line 5-5 of Fig'- ure 3.

Figure 6 is a sectional detail of the means for joining the top and sides of the swingable member.

Figure 7 is a section on line 7 7 ot Fig-y ure 3.

Figure .8 is a plan View of the anchoring member of the hoist7 partly in section.

Figure 9 is a sectional detail, showing telescopic construction of the anchoring member.

Figure 10 is a perspective detail ot the engaging supporting` bars of the anchoring' member.

Figure 11 is a perspective view ci the top cross bai'.

Figure 12 is a sectional detail oit the reseit/'ing` bar showing' holes for adjusting the telescopic bar therein.

Figure 13 is a plan View oi the floor plate.

Figure 1s is a longitudinal section of the door plate.

in the drawings and referring more particularly to Figures 1 and 2;

A. designates the hoist as a whole, set up in a window B carrying a load in thc torni or crate C. My improved hoist consists essentially ot an outside or swingable meinber 1U and inside or anchoring member 11. The outside or hoist member consists 0i. a bar inwardly slopingl from the bottom7 hollow bars or pipes 12 and 13 'forming the sides and connected at the top by a cross pipe 1-l, adapted to engage with suitably bent solid ends 15 and 16 of the sides 12 and 13 and bolted thereto at 17 and 18. The bottom of the side pipes 12 and 13 are edte receive therein the solid elbows 19 and 2O of the base cross pipe 20 formed with a central oiiset therein 21, the elbows 19 and 20 being bolted in to the sides 12 and 18 at 22 and 23 on the sides 19. and 13, and clevis members 2i and 25 to which are attached chains and 27 provided with gripping hooks 28 and 29 adapted to engage with the anchoring or inside member oit' the hoist as hereinafter more fully described. Substantially midway of the cross pipe 1st. is a clevis 30 to which is attached the hoisting tackle comprising a block and line 32.

From the foregoing` it will be seen that the sides 12 and 13 are swingingly mounted in the base cross pipe 20, thus enabling,r the hoist to be swung,r outwardly or inwardly as may be desired in operation, while te dis mantle the hoist it is only necessary to unscrew the securing bolts for the sides and top and the whole hoisting member is readily talren apart.

Referring now more particularly to the anchoring member 11, this consists of a Hoor plate 33 provided with a plurality of counter sunk apertures 34; and designed to bc placed on the floor on the inside of a window. Into the holes 34 are fitted Vertical and tubular posts 35 and 36 provided with a 4 plurality oi spaced holes 3i" and into these posts are designed to slid-ably lit the supl0 therein adapted to register individually with the oaeninos 37 and to receive therethrough securing` bolts whereby the bars 38 and 39 are tixedly secured at any required height.

On the top ot these bars or posts is a cross piece il provided with a plurality oi openings 4t2 registering with the openings 3ftin the tloor plate 33 and adapted to receive therein the supporting side bars and 256, the ends ot the posts SSfand 39 being pin formed at 4l?) t0 engage with the openings l2 individually whereby in combination with the openings in the iloor plate the telescopic supporting` sides are adapted to be adjusted to any required width.

0n the sides are chains 26 and 27 tor i'lexibly securing the hoisting` member to the anchoring member and also to limit the outward travel ot the former. To prevent the hoisting member from slipping, embracing straps lf-l are provided to bind it to the anchorinp,` member.

From the foregoing the operation ot my device will be apparent. lThe anchoring member is iirst litted on the inside oi' a window, having been adjusted longitudinally and horizontally to register with the window space. The hoist member is then asembled and also adjusted to the size of the window soace. lt is then placedl on the window sill outside or on the window ledge, as the case may be, and secured in the bottom to the anchorino' member by means of straps, while the upper portion is also 'flexibly secured to the top of the anchoring` member by the hoist chains carried by the hoist. rlhe block and tackle completev the equipment ot the hoist. The object to be hoisted, having been connected thereto, is drawn slowlyup and when it reaches a position-outside of the window space, the hoist member is swung' inwardly carrying the object with it and delivering it without any risk to the operators within the building.

As many changes could be made in the above construction and many apparently widely ditlerent embodiments of my invention, within the scope of the claims, con structed without departing from the spirit or scope thereof, it intended that all matter contained in the accompanying specification and drawings shall be interpreted as illustrative and not in a limiting sense.

What I claim as my invention is: Y

l. ln a device of the character described and in combination, a hoisting trame comprising a hollow base bar having an ollset intermediate ot its length, hollow side bars, elbows pivotally connecting the side bars with the base bar, a hollow top bar, elbows rigidly connecting,` the top bar with the side bars, chains suitably mounted on the side hars, an anchoring member and flexible binding means tor the anchoring` member and the hoisting trame.

2. In a device of the character described and in combination a swingly mounted hoisting member, an anchoring member flexibly connected to the hoisting member and comprising a floor-plate having a plurality of counter sunlr oriiices therein, hollow side posts adapted to engage with said plate and means formed in the posts adapted to engage retaining means for posts, whereby the latter are adjusted, a top plate having oriiices therein registering with the orifices in the licor-plate and adapted to engage with Asaid side posts and chain means for clamping the top plate and the side posts together.

3. in a device of the character described, the combination with a rigidly constructed and swingingly mounted hoisting frame or" an anchoring frame formed of telescopic side posts and top and bottom orificed plates designed to engage with said posts, whereby the width of the trame is adjustable and the height ot the trame through the telescopic side post-s is also adjustable. Y

ll. In a device ot the character descbcd, the combination with a hoist-ing trame, or" an anchoring frame formed of telescopic sides and oriiced top and bottom plates adapted to adjustably and detachably engage with said sides.

In witness whereof l have hereunto set my hand.

JOSEPH BROADHEAD.
